Clinical trials

The European Union Clinical Trials Register   allows you to search for protocol and results information on:
  • interventional clinical trials that were approved in the European Union (EU)/European Economic Area (EEA) under the Clinical Trials Directive 2001/20/EC
  • clinical trials conducted outside the EU/EEA that are linked to European paediatric-medicine development

    • EU/EEA interventional clinical trials approved under or transitioned to the Clinical Trial Regulation 536/2014 are publicly accessible through the
    Clinical Trials Information System (CTIS).

    The EU Clinical Trials Register currently displays   43865   clinical trials with a EudraCT protocol, of which   7286   are clinical trials conducted with subjects less than 18 years old.   The register also displays information on   18700   older paediatric trials (in scope of Article 45 of the Paediatric Regulation (EC) No 1901/2006).

    Phase 1 trials conducted solely on adults and that are not part of an agreed paediatric investigation plan (PIP) are not publicly available (see Frequently Asked Questions ).  
     
    Examples: Cancer AND drug name. Pneumonia AND sponsor name.

    E. General Information on the Trial
    E.1 Medical condition or disease under investigation
    E.1.1Medical condition(s) being investigated
    This is a study of the anesthetic effect of the IMP, nitrous oxide. In this sense "general anesthesia" can be termed the medical condition under investigation.
    MedDRA Classification
    E.1.3Condition being studied is a rare disease No
    E.2 Objective of the trial
    E.2.1Main objective of the trial
    The main objective of the trial is to quantify the reduction of the propofol consumption when nitrous oxide is used in addition to a propofol-remifentanil anesthetic.
    Nitrous oxide has been traditionally used as an adjunct to almost all forms of general anesthesia in order to reduce the consumption of the other anesthetic drugs, but it has side effects of its own and is a greenhouse gas. From the literature, it is not clear to what extent the addition of nitrous oxide can actually reduce the consumption of intravenous drugs such as propofol.
    E.2.2Secondary objectives of the trial
    - To quantify the reduction of remifentanil consumption by nitrous oxide.
    - To test whether the addition of nitrous oxide to a propofol-remifentanil anesthetic can reduce the recovery time.
    E.2.3Trial contains a sub-study No
    E.3Principal inclusion criteria
    - necessity of a general anesthesia with controlled ventilation
    - age of consent (18 years) reached
    - informed consent to study
    E.4Principal exclusion criteria
    - pregnancy
    - planned duration of surgery more than 6 hours
    - psychotropic therapy
    - allergy to a general anesthetic used or to muscle relaxants
    - CNS disease
    - previous general anesthesia in the last month
    - known anomalies in the blood count
    E.5 End points
    E.5.1Primary end point(s)
    - consumption of propofol

    secondary end points:
    - consumption of remifentanil
    - recovery time (end of propofol application until extubation)
    - number of hemodynamic alterations with therapeutic consequences during anesthesia
    - volume infused and blood units transfused
    - dose of catecholamines required
    - percentage of bispectral index in the adequate range of 40-60
    - incidence of intraoperative memory formation

    E.8.8 Definition of the end of the trial and justification where it is not the last visit of the last subject undergoing the trial
    There is no foreseeable reason why this trial should be ended before the last subject is enrolled, since anesthesia has been performed with and without nitrous oxide for many decades already.

This trial was recorded in the database on 2007-07-02. Yes
